FEATURES  
DESCRIPTION  
The AMC1203 is a 1-bit, 10MHz, isolated delta-sigma  
(ΔΣ) modulator with an output buffer separated from  
the input interface circuitry by a silicon dioxide (SiO2)  
isolation barrier. This barrier provides galvanic  
isolation of up to 4000VPEAK. Used in conjunction with  
isolated power supplies, these devices prevent noise  
currents on a data bus or other circuits from entering  
the local ground and interfering with or damaging  
sensitive circuitry.

16-Bit Resolution  
SNR: 80.5dB min  
THD: –88dB max (AMC1203B)  
±280mV Input Range with +5V Supply  
Internal 2.5V Reference Voltage: 1% Accuracy  
Gain Error: ±1% (AMC1203B)  
UL1577, IEC60747-5-2 (VDE0884, Rev. 2), and  
IEC61010-1 Approved  
The AMC1203 modulator operates from a +5V supply  
with a dynamic range of 95dB. The differential inputs  
are ideal for direct connection to shunt resistors or  
other low-level signal sources. With the appropriate  
digital filter and modulator rate, the device can be  
used to achieve 16-bit analog-to-digital (A/D)  
conversion with no missing codes. An effective  
resolution of 14 bits and an SNR of 85dB (typical)  
can be maintained with a sinc3 filter with a decimation  
ratio of 256.

APPLICATIONS  
•
Shunt Based Current Sensing in:  
The modulator output is translated to a balanced  
signal and then transferred by the capacitive isolation  
barrier. Across the isolation barrier, a differential  
comparator receives the logic transition information,  
and then sets or resets a flip-flop and the output  
circuit accordingly.
